I Love Lucy - Season 4 - Eps 15: Ethel's Home Town
The Ricardos and the Mertzes stop at Ethel's hometown: Albuquerque, New Mexico (Vivian Vance's real-life hometown). Under the impression that Ethel has been called to Hollywood and not Ricky, the townsfolk accord her a monumental ovation. When Ethel refuses to disillusion them -- and even goes so far as to put on a "celebrity act" -- Lucy takes matters into her own hands.
